ICE CRACKING AND SHAVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 569,250, dated October 13, 1896.

Application tiled January 24, 1896. Serial No. 576,712. (No model.)

To all whom it may concern,.-

Be it known that I, FREDERICK EUGENE STEERE, of Lynchburg, in the county of Campbell and State of Virginia, have invented a new and Improved Ice Cracking and Shaving Machine, of which the following is a full, clear, and exact description.

This invention relates to machines for cracking or shaving ice as required for use in sodawater or similar beverages 5 and the object of the invention is to provide a machine that may be readily operated for the purpose, and which may be quickly changed into operative positions for use in either shavingvor cracking the ice.

I will describe a machine embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a top view of a machine embodying my invention. Fig. 2 is a vertical section thereof, showing the parts in position for cracking ice. Fig. 3 is a similar section showing the parts in position for shaving ice. Fig. 4L is a section on the line l 4 of Fig. 3. Fig. 5 is a face view of an ice-cracking device employed. Fig. 6 is an edge view of a shaving device employed, and Fig. 7 is a section on the line 7 7 of Eig. 2.

Referring to the drawings, A designates a hopper, made substantially in the form of a segment of a circle, open at its upper end and having a head a closing its lower end. The lower end portion has openings a', through which cracked ice may fall into a drawer or receiver a2, placed in the base A, and there is also an opening a3, through which shaved ice may fall into the said drawer or receiver.

A2 is a plunger consisting of a disk having spikes or projections on its front face and having an arm d, connecting at its upper end with a lever A3, pivoted to a lug extended upward from the top wall of the hopper A, so that by operating this lever As the plunger A2 may be moved into or out of the hopper.

B is a knife-carrying disk mounted on a shaft b, extended outward through a tubular projection ZJ', extended from the head d, and having at its outer end a crank-wheel b2. The

inner face of this disk B is provided with blades b3, adapted to shave ice from achunk pressed against them by means of the plunger A2, and the central portion of this disk B may be provided with a spike-like projection b4, designed to break up or crack ice that may be missed by cracking-teeth b5, extended from the disk B, mounted on a sleeve b, surrounding the shaft b and adapted to move longitudinally thereof, so as to project the teeth b5 through holes formed in the disk B.

Longitudinal movement is imparted to the sleeve Z2 to move the teeth b5 into or out of the openings in the disk B by means of a segment-gear C, mounted on a pivoted lever c and engaging with a rack c', loosely mounted on the upper side of the sleeve h6 and having a lug c2 at one end designed to engage in an annular channel formed in the sleeve b"`,whereby said sleeve may be moved with the rack, but is allowed to rotate freely with relation thereto.

As a means to lock the disk B in its operative position I employ the spring yielding bar C', attached at one end to the casing or hop.

per-shell and having at its opposite end a pin c3, adapted to engage in an opening in the lever c.

In operation the plunger A2 is moved out of the hopper, as indicated in dotted lines in Fig. 2, and the ice is placed in the hopper. Thensaid ice is forced against the teeth b5, which, when the parts are rotated, will crack or break the ice in small pieces, which pieces will fall into the receiver a2. Should it be desired to shave the ice, however, the disk B is moved outward, and then upon rotating the parts the knives or cutters b3 will do the shaving.

A finger c, extended from the lever A3 near its pivotal point, will engage with the lugs to which said lever is pivoted and prevent the said lever from moving too far upward, or serve to support said lever out of engagement with the crank-wheel.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. An ice shaving and cracking machine, comprising a hopper, a plunger mounted in said hopper, a rotary shaft, a disk mounted on said shaft, knives carried by said disk, another disk mounted on a sleeve surround- IOO ing and movable longitudinally on the rotary shaft, spikes extended from said last-named disk and adapted to be passed through open- 'ings in the first-named disk, and means for moving the spike-carrying disk longitudinally of the rotary shaft, substantially as specied.

2. An ice cracking and shaving machine, comprising a hopper having openings in its lower side, a receiver below said openings, a plunger movable in said hopper, a rotary shaft, a cutter-carrying disk mounted on the said shaft Within the hopper, a spike-carry ing disk mounted on a sleeve movable longitudinally of the rotary shaft, a rack loosely mounted on the said sleeve and having a lug projecting into an annular groove in the sleeve, a fulcrumed lever having a segmentgear engaging the said rack, and means for locking said lever, substantially as specified.

3. The combination of a hopper, a plungermovable therein, a rotary shaft, a disk mounted on the shaft and provided with knives, and another disk movable longitudinally of said rotary shaft, and provided with spikes adapted to engage the ice beyond the iirst-mentioned disk, substantially as set forth.

4. The combination of a hopper, a plunger movable therein, a rotary shaft, a disk carried thereon and provided with knives, a sleeve movable longitudinally on and adapted to turn with the shaft, a disk carried on said sleeve, spikes carried on said last-named disk and adapted to crack the ice, and means for moving the sleeve longitudinally on the shaft, substantially as set forth.

FREDERICK EUGENE STEERE.
